METHOD OF AND APPLIANCE FOR REGISTERING.

Application filed February 23, 1923. Serial No. 620,750.

To all whom it may concern:

Be it known that I, CLARENCE B. SMITH, a citizen of the United States, and a resident of Winthrop, in the county of Suffolk and Commonwealth of Massachusetts, have invented certain new and useful Improvement in Methods of and Appliances for Registering, of which the following is a full, clear, and exact specification.

This invention has especial reference to embossing presses, but it is also applicable to other forms of printing where it is desired to have a plurality of impressions accurately register. Previous to 'my invention it has been the custom, after having printed the sheets of paper, as letter heads or cards, sheet after sheet is positioned on the embossing press until finally the em bossing is made to register with the printing, an operation often lasting for half an hour.

The object of my invention is the development of a process and means whereby such registering can be accurately made in but two or three minutes and far more perfectly than by the former method. My method consists essentially in mounting upon the board of the embossing machine a more or less transparent sheet; embossing the same with the dies to be used; locating upon the same a sheet of the printed paper or card; shift-ing it until, by means of light through the two sheets, the printing is seen to be in exact register with the embossing, and then inserting pins or blocks into the board at two edges of the paper or card so that the remaining sheets to be embossed will be properly located for equally accurate embossing.

In the drawings forming part of this specification, Fig. 1 is a side elevation of an embossing press. Fig. 2 is a perspective view of the board of the press removed therefrom. Fig. 3 is a plan view of the board showing certain steps of the process. Fig. i is a sectional view of the board, showing a means for delivering light through the two sheets thereon.

The embossing machine illustrated is of well known form, comprising engraved die, 1, counter 2, means, as 3, for the actuation of the male die, and a board 4: upon which the paper or card board is placed to be embossed. This board has a notch 5 to make room for the dies, and is removable from the press, being provided with pins 6 fitting in holes in the frame work 7 for enabling it to be accurately positioned.

In my preferred method, I attach over the notch 5, as by pins or tacks 9, a thin piece of paper, card board or other more or less translucent material 10, as shown in Fig. 2. The press is then put into operation and the sheet 10 embossed, the embossing being indicated by the dotted circle 11.

If the printed paper to be embossed is very thin, and the sheet 10 transparent, it may be possible to register the work with out removing the board from the press.-

It is much better, however, to remove the board 4 and to place it where rays of light can shine up through the notch 5, as from an electric bulb 12 shown in Fig. 4.

One of the printed sheets 13 being placed upon the board, is shifted thereon until its printed portions, as the concentric circles 14, are seen to be in exact register over the dotted figure 11. Then register blocks 15 or other sheet-looalizing means are attached to the board at two edges of the sheet 13, whereby all the other printed sheets when placed against the same will accurately register with the embossing.

The sheet 10 can now be removed and the board returned to the press, after which the work of embossing the printed sheets can proceed as usual.

For heavy paper and card board, it is absolutely necessary to remove the board 4 and support its notch 5 in, front of a bright light 12 in order to see through the two thicknesses clearly enough to register the two impressions. Without my method, it is requisite that a considerable number of printed sheets be embossed, their positions located by pins, each removed for careful consideration to determine if the register is nearer; if not exact, the pins are removed and another test made in the same manner. This usually consumes a great deal of time on the part of the printer,

and keeps the press unavailable for the same length of time.

Although I have above spoken of embossing as the treatment to the paper or card board 13 given by the dies 1, 2, yet it is customary to have the embossing accomanied with color-application simultaneous ly therewith. Hence I do not restrict myself to embossing alone, or to color work additional to the embossing, since the impressioifsgiveii the prssmjmbis may be iii Blaek or in an'ydesired dolor.

What I claim is:

- 1. The n1eth0dof registry consisting in fastening a thin sheet in the path of the impression Inembersof press, impressing said sheet, illuminating the under surface of the latter, registering with said impres-' sion asheet ofthe printed matter designed i fblyirniife sed; and Providing means 1551- 1,477,392 1 g I V registering the latter with said embossing, loea lizi'iig edges of said "ip rin'te'fd-sheet, restoring said board to its exact former position', removing the first printed sheet, and

then embossingv the, other printed sheets in registry therewith.

31-Theeoinbiiiaion 'vvith the removable board of, an embossing press, havin 'an opening for the action or the dies 0 the press, of a sheetthro igh Which light can penetrate attached to said board over said opening, whereby said sheet having been embossed its under: "siirface illuminated, afsheet ofprintied matter can be put in registry 'With the embossing dies.
